Carbohydrates (carbs). Lipids (fats) are an example of carbs, and, when you burn them, you lose weight.
less fat
Your motabalism and the amount of carbs, fat and calories you take in everyday
They have a bit more than twice the calories of carbs & proteins per unit weight.
Olive oil is a food that has calories but no carbs or protein.
bacardi rum has 50 calories per shot, obviously without mixer and has no carbs!! drink on my friend!!!
They are based on lowering your calorie intake, be it by lowering carbs, fats, calories in general, or eating foods that are lower in calories but keep you fuller longer. Reducing your calories can help result in weight loss.
The Atkins diet is built on restricting carbs and filling up on fats. This puts your body in a state of ketosis so your body learns to burn fat for energy instead of carbs. It does cause weight loss but personally I wouldn't recommend it. You need carbs in your diet.
Yes You can lose weight eating anything as long as you are burning more calories than you are taking in.
Yes, you can gain weight if you eat too many calories total, no matter which type of calorie (fat, carb, or protein). However, fat counts for 9 calories per gram wheras carbs and protein are 4 calories per gram. So you can (and should) eat plenty of complex carbs and lean protein, while keeping fat intake down, and not worry about gaining weight.
Any time you keep below 50 carbs a day, and 1,200-1,300 calories you'll lose weight. If you are very active you can usually afford more calories but from my personal experience keep the carbs low. Plan on losing 2 lbs a week and you'll be able to keep it off too. When you're ready to maintain your weight just slowly add carbs and calories until you even out.
